Morrison's attorney made her opening argument, but Mitchell?s attorney declined to have an opening argument.

The other teen, Jevontai Ingram, escaped but was later captured and took the stand in the case.

Parker's family spent the entire day in the courtroom. Family members said they've been waiting two years for the pair to stand trial.

"This just needs to be over with. They need to go ahead and convict them of what they are truly guilty of, and that is murder," Parker's aunt, Mona Stewart, said.

During his testimony, Ingram said the teens were going to "get some pills and sell them for $1,500 a piece."

Parker's family said the teens deserve to spend life in prison because Parker lost his life in the botched robbery.

"We miss him! You know every day seeing him, going to school he was a good kid. He wasn't a bad kid. He wasn't the kind of kid that went around doing things like that. Those guys coerced him. That's the bottom line," Stewart said.

Morrison and Mitchell's attorneys argued they are not the men responsible for killing Parker; that the responsibility for his death is Ersland's alone.

The defense attorneys also said Ingram is changing his story about the robbery.

Ingram has already pleaded guilty in the case in juvenile court. He could be released when he is 18 1/2 if he completes a treatment plan.
